MR1025R On-Grid Photovoltaic Trainer Vocational Training Tools And Equipment University Equipment Photovoltaic Generator Trainer 1.Product Introduction 1.1 Product Description The whole process of photovoltaic power generation grid-connected operation is fully restored, so that operators can not only master the basic principles of power generation, but also deeply understand advanced knowledge such as grid interaction and energy dispatching, providing more comprehensive practical training support for the design and application of new energy power systems. 1.2 Product Features 1. Grid-connected coverage, in-depth teaching upgrade Grid-connected system, students can analyze the working principle, efficiency and applicable scenarios of the mode. Supports real grid interaction logic demonstrations such as "self-generation and self-use" and "surplus power grid connection", close to the actual operation of photovoltaic power stations. 2. Safe grid-connected design The grid-connected inverter has anti-reverse flow protection, overvoltage/undervoltage protection, and anti-islanding protection to ensure the safety of grid simulation experiments. Emergency stop switch, circuit breaker and graded fuse (5A/10A/20A) are retained, and double protection is adapted to high-power grid-connected scenarios. 3. Strong compatibility and flexible expansion Connect the grid simulation interface through the K4 test line, and the grid-connected function expansion can be realized without additional modification. 4. Comply with industry standards Grid-connected parameters (voltage, frequency, harmonics) strictly match grid specifications to help students master the actual grid-connected technical requirements. 2.
